Bought a 2005 Yukon and whenever I am above 50 mph there is a faint fast click or engine knock if you will. More of a click or ticking sound than a knock per se. Rides and accelerates fine but wondering if this is normal or not?

Is it a constant ticking, and does it match the speed of the engine? If so, that's pretty common, my Z06 does the same thing.

I am not that menchanically inclined but I think it matches the engine. I was reading the manual and it said somewhere in there that some engine knock was normal and does not indicate a need for higher octane gas.
